摘要：
Photoluminescence and optical absorption spectra induced by proton and electron irradiation in zinc oxide powders have been investigated. It has been found that the emission band in a visible region with a maximum of about 2.3 eV is a superposition of three bands with 2.55, 2.34, 2.12 eV, respectively, caused by oxygen vacancies VO+, interstitial oxygen Oi−, and zinc vacancies VZn− absorbing in the 3.03-, 2.83-, and 2.64-eV bands.
